HARRY SEMPLE, OF HAMILTON, ONTARIO, CANADA.

MACHINE FOR FINISHING BOTTLE-NECKS.

SPECIFICATION forming part of Letters Patent No. 384,290, dated June 12, 1888.

Application filed November 14, 1887. Serial No. 255.152.

To aZZ whom it may concern.-

Be it known that I, HARRY SEMPLE, a citi zen of Canada, residing at Hamilton, in the county of Wcntworth, Province of Ontario, Canada, have invented a new and useful Machine for FinishingBottle-Necks, of which the following is a specification.

My invention relates to improvements in bottle-finishing machines in which a shaft oscillates in a head-stock with and in conjunction with rotary arms.

The objects of my improvements are, first, to provide an adjustable oscillating ping for the purpose of fittinginto the neck of a bottle 5 while hot, and, second, to afford facilities for the operation of two adjustable oscillating jaws engaging with the bottle-neck and shaping the same. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation of an entire ma chine. Fig. 2 is an end elevation of the ma chine through the center of head-stock, and Fig. 3 is an end and side elevation of armgnide and socket.

Similar letters refer to si milar parts throughout the several views.

The table or plate A, with head-stock 0 secured on the top, and the standards B, eonsti; tute the frame-work of the machine.

In the right-hand end of the shaft E, in bearings of head-stock, is a plug, E, oscillated by the drive-pulley 1) by means of an eccentric, F, with rod F, which gives an oscillating mo- 5 tion to the toothed segment-lever G, working in the fulcrum H, and transmitting power of an oscillating form to the toothed wheel I on shaft E, thus oscillating said shaft, which may extend out from left hand of headstock, thus forming a double machine.

(No model.)

When the rod J is brought toward the headstock by means of collar P engaging against the nut-locked rest J, the said jaws close on the neck of the bottle 0 by means of the clutch lever L in clutch L", closing the arms M. The knuckle j oints N are so arranged that thejaws N, having a round shank on the end, can be held firmly and adjusted by means of setscrews, and set to any angle by said knucklejoint. WVhen the said rod is moved in an opposite directiomthe saidjaws, which are socketed in the socket-guides M, open out, on the principle ofgovernors, thus throwing the feedrod J back by the expansion of the arms.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a bottle-finishing machine, the combination of an oscillating shaft, E, one end of which is provided with an adjustable plug for shaping the inside of bottlenecks, substantially as and for the purpose hereinbcfore described.

2. In a bottle-finishingmachine, the combination of an oscillating shaft provided with a clutch, L, collar L, socket-guide M, arms M, knuckle-joints N, and adjustable jaws N, substantially as and for the purpose specified.

3. In a bottle-finishing machine, the combination of an oscillating shaft, E, with plug E,
